Chipmunk Hunk possesses a chipmunk-themed version of Squirrel Girl’s powers: the enhanced strength, speed, and agility of a chipmunk. Tomas can also communicate with chipmunks; eventually, Doreen taught him and the others how to speak to squirrels. Finally, Tomas possesses a chipmunk-like tail, hidden when in his civilian identity.

It’s unknown whether Tomas is a mutant, an Inhuman, or some other origin. However, given current Marvel events, it’s likely a vaguely defined origin, similar to Doreen’s current status quo.
